“…This result is in agreement with the literature, in which malposture of the extremities accounted for 41% of equine dystocia [ 6 ]. Differently from what is reported in Thoroughbred foaling [ 46 ], feto-maternal disproportion due to fetal oversize was not observed. In fact, the median foal weight was within normal range for foals of average size.…”

Dystocia as a prolonged stage II parturition (>30 min) was associated with a higher risk of complications. The hypothesis of the study was that any type of dystocia could affect the foal’s health, even when the stage II was <30 min. Clinical reports on 222 Standardbred mares and their foals hospitalized at the Veterinary Teaching Hospital of the University of Bologna from 2004 to 2020 were reviewed. Mares were divided into the Eutocia Group (165, eutocic delivery) and the Dystocia Group (57, dystocic delivery). The incidence of dystocia was 4.9%. Stage II was longer in the Dystocia Group (median 20 min) than in the Eutocia Group (median 12 min). All occurrences of dystocia were retrospectively classified into three categories of severity: mild, moderate and severe dystocia. The occurrence of postpartum complications in mares and neonatal diseases and failure of passive transfer of immunity in foals was higher in the Dystocia Group. Foal venous lactatemia and serum creatine kinase were significantly higher in the Dystocia Group (median 3.9 mmol/L; 262 UI/L respectively) than in the Eutocia Group (median 3.1 mmol/L; 187 UI/L respectively). The APGAR score was lower in the Dystocia Group (median 8) than in the Eutocia Group (median 10) and significantly lower in severe dystocia (median 3). The duration of stage II should not be considered the only parameter of dystocia in mares: even a rapid resolution of dystocia could pose health risks to the foal and the mare.

“…As recently reported [33], normal gestation length in the THB mares included in this study ranged between 330 and 396 days, with a mean of 352 days. All THB included in the present study were housed in the Waikato region, New Zealand, where the hours of daylight ranged from 11.20 to [12] is that the equine uterus needs to be in some way primed by a first pregnancy before it can achieve its full potential in terms of facilitating fetal growth.…”

“…Four to six hours post-partum have also been proposed as still being within the physiological range ( 7 , 22 ). Personal communications suggest that some specialist theriogeniologists already consider membranes retained if not expulsed by 1 h post-partum, which is supported by the findings of a recent study that reported fetal membrane release within 1 h in two-thirds of mares ( 5 ).…”

“…The duration of time before the membranes are considered to be retained varies widely from 30 min to up to 24 h ( 2 – 4 ). A recent study found that 95% of Thoroughbred mares expelled their membranes within 4 h, whereby more than two-thirds of the mares had already expelled them after 1 h ( 5 ).…”

Treatment of Retained Fetal Membranes in the Mare—A Practitioner Survey

et al. 2018

View full text Add to dashboard Cite

Retained fetal membranes (RFM) is a common post-partum problem in mares for which the treatment is highly variable. The aim of this study was (i) to investigate the different treatments used by equine practitioners for RFM and (ii) to determine if there is a difference between treatments used by reproductive specialists and general equine practitioners. Information regarding treatment of RFM was sought from veterinary practitioners via a survey and this was compared to recommendations in the current literature. The survey was sent out to equine veterinarians and mixed practitioners with a high equine case load. Most treatments of RFM were in line with current recommendations, while some obsolete practices are still routinely performed by a small number of practitioners. Treatment recommendations for RFM have changed over the last few decades, but there are no universally accepted guidelines. The vast variety of treatments reported by practitioners in the present survey reflect this lack of guidance. More extensive research is needed in this area to establish evidence-based, uniformly agreed upon protocols.
